IMPROVEMENT IN SKY-LIGHTS.

*OFO- The Srhedule referred to in A'these Letters Patent and making part of the same.

I, SAMUEL P. SNEAD, of the city of Louisville, in the county of J elierson and State of Kentucky, have invented a certain new and nsefnl Improvement in Hemispherical or Spherical Glass Sky-Lightswfor one inch from this ange is another similar ange about one inch high, leaving aspace between them, forming a gutter for the purpose of catching and oonducting to the roof, through the holes in the outer ange, all water that may collect from condensation, orotherwise, on' the inside of the glass. This lastnanled fiange is Amade thicker than` the other, and rabbeted ont. ou the inside about one-half of its thickness and depth, leaving a shoulder at the bottom the same height as the inside Bange, for the end of the glass sphere to rest on, while it is secured by putty or other material between the liange -and glass on `the out-side, which renders it perfectly water-tig'fht.Y The glass used in this invention may be either spherical, circular, angular, or segment.

Figure 1 in the drawing is a view ofthe plate and glass.

Figure 2 is a sectional view, lwhen cut through the center..

A is the plate or frame, andis made of cast-iron.

B is the outer flange. l

C is the rabbet in which the glass is secured.

, G is the putty or other material by means of which y it is made Water-tight.

D D D are the holes through the flange below, by means of which the water is conducted from the inner glitter to the roof.

F is the gutter formed by t-lie flange E and -shoulder (l.

H is the glass, which is made in the form of a sphere, but may be made inthe form of a sphere, a sp hel-ical segment, or any other circular or angular shape desired.

Having thus fully described the drawing,

I claim as my invention- 'lhe frame A, with the inner flanges E, shouldered anges B O, provided with,escape-openings D D and the gutter l, and a glass, H, secured on the shoulder C, all as herein described, for the purposel specified.
